Cellphones and batteries. It's an eternal struggle, but one that Google's Larry Page says should at least be manageable. That topic arose at the recent Google Zeitgeist forum, where Page responded to a question about battery life on Android phones by saying that he actually found it to be "pretty good," and that "if you are not getting a day, there is something wrong." That prompted Google CEO Eric Schmidt to chime in and explain that the main culprit for excessive battery use on the phones is the transmit / receive circuit, which he says some apps are "not particularly smart about" using.
